Provides superior support and comfort for the ankle and foot. Closely spaced eyelets in the middle concentrate the holding power where it is needed most. Outside offset flaps pull the ankle into a stable position and hold it securely. When laced tightly, the stainless steel, U-shaped, spiral-wound stays provide extra support and further minimize the chance for ankle injury. Available with a padded or knit tongue. When more medial/lateral support is needed, an optional Universal Stabilizer can be inserted into pockets on either side of the brace. Measurements correspond to shoe size.
